Silver-grey or dark grey powder, metal silicon has a high melting point, good heat resistance, high resistivity, and exceptional oxidation resistance. It also has a metallic sheen. It is referred to as “industrial glutamic acid” and is a crucial fundamental raw ingredient for sophisticated industry.

How Is Silicon Added During the Production of Aluminium Alloys?
(1) Add the metal silicon 553 directly. The precise procedure is to distribute silicon blocks across the furnace’s bottom, place aluminium ingots on top of the silicon blocks, add aluminium water, light the fire, and then raise the temperature to melt the silicon blocks.
(2) Employ an alloy master. The precise procedure is to either put it straight into the aluminium water or lay it out on the furnace bottom, light it, heat it and melt it.
(3) Incorporate silicon powder.
(4) Add silicon that melts quickly. When the temperature rises above 720°C, the precise procedure is to immediately sprinkle aluminium water into the furnace and wait for the silicon, which melts quickly, to entirely melt.
Nowadays, Type 1 and Type 4 silicon addition techniques are the most used among them. After being crushed, metallic silicon 553 with a particle size of 20–100 mm is used as the raw material for both fast-melting silicon and metallic silicon. Electrolytic metal production is the method used. A jaw crusher is used to crush and sift silicon ingots to create goods. However, because of its low yield and delayed melting or insolubilization, metallic silicon (553 below 20 mm) is discarded. The diameter of silicon powder utilised in current technology to create fast-melting silicon ranges from 20 to 80 mm. Consequently, it is imperative to develop a technical approach that addresses the use of metal silicon 553 below 20 mm in aluminium alloy smelting.
What Is the Difference Between Metal Silicon 441 and 553?
In our nation, metallic silicon is often categorized based on the amounts of its three primary impurities—calcium, aluminium, and iron. Metallic silicon can be classified into several grades, such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101, based on the proportion of iron, aluminium, and calcium in it. For example, 553 indicates the content of iron, aluminium, and calcium in metallic silicon, which is 0.5% and 0.5%, respectively; 441 indicates the content of iron, aluminium, and calcium in metallic silicon, which is 0.4%, 0.4%, and 0.1%. In each grade, the first and second codes indicate the percentage content of iron and aluminium, and the third and fourth digits represent the calcium content.
Consequently, the purity difference between 441 and 553 is what separates them. 553 has a silicon content of ≥98.7%, whereas 441 has a silicon content of ≥99.1%. In particular, quartz and carbon react at a high temperature in a submerged furnace to produce industrial silicon: SIO2 + C= SI + CO2. As with the grade of quartz, the quality of carbon used as a reducing agent can likewise vary widely. The purity of industrial silicon is determined by the variations in these basic ingredients. From a financial standpoint, higher-quality raw materials will cost more.
What Is The Application Value of Metallic Silicon 553?
- Alloys: Aluminium alloys, stainless steel, and other metal alloys are frequently made using silicon metal 553 as an alloying agent. These materials become stronger, harder, and more resistant to corrosion as a result.
- Semiconductors: The main raw material used to make these vital parts of electronics, which include integrated circuits, computers, and cellphones, is silicon. Due to its semiconducting qualities, silicon is an essential component in the electronics sector.
- Solar Cells: A crucial component in the creation of solar cells is silicon. Photovoltaic cells, which turn sunlight into electricity, are made with it. Silicon is the perfect material for solar energy generation because of its efficient ability to absorb and transform sunlight.
- Chemical Industry: Silicon metal 553 is used as a raw material in the chemical industry to make a variety of chemicals based on silicon. Silicone polymers, sealants, adhesives, lubricants, and other chemical products are made with these chemicals.
- Refractories: It is employed in the manufacturing of heat-resistant materials known as refractories, which are utilized in high-temperature settings including foundries, kilns, and furnaces.
- Metallurgical sector: The metallurgical sector uses silicon metal 553 for alloying and deoxidation processes. It enhances the mechanical qualities of molten metals and aids in the removal of impurities.
